Definitions
- the present invention concerns a process for the production of an organic electrolyte electric cell with a unitary structure.
- a cell with a unitary structure is a cell in which the elements constituting it, in particular the electrodes and the separator, are integral so that each element follows all of the dimensional variants of the cell during its operation.
- a number of prior art documents propose a process for the production of a cell with a unitary structure which uses a plasticizing additive during assembly of the elements of the cell.
- U.S. Pat. No. 5,456,600 describes a process for the production of a cell with a unitary structure which consists of adhering the cell elements, namely the electrodes, the separator and optionally the collectors, by rolling.
- Each element of the cell is in the form of a polymeric film, preferably based on a copolymer of polyvinylidene fluoride and hexafluoropropylene (PVDF-HFP).
- the separator and optionally the other elements of the cell contain a plasticizer which conserves the microstructure of the elements during rolling. The plasticizer is then eliminated by extracting it with a selective solvent.
- a first electrode is constituted by a conductive support on which a paste containing a polymer, a plasticizing additive and an electrochemically active material are deposited.
- the polymer is preferably a copolymer of polyvinylidene fluoride and hexafluoropropylene (PVDF-HFP). After drying, the electrode is coated with a film which constitutes the separator. The electrode-separator assembly is then coated with a second electrode and heated under pressure.
- the plasticizer is then extracted using a solvent which is inert towards the polymer.
- the aim of the present invention is to provide a process for the production of an organic electrolyte electric cell with a unitary structure:
- the present invention thus provides a process for the production of an organic electrolyte electric cell with a unitary structure comprising at least one pair of electrodes comprising:
- a first electrode comprising the superposition of a first layer containing an electrochemically active material and a porous second layer of a polymeric material having a free face;
- a second electrode comprising a porous layer having at least one free face and containing an electrochemically active material
- the electrodes are assembled by adhesive bonding, bonding being carried out by coating an adhesive onto the free face of the porous layer of one of the two electrodes and then bringing the free face coated with a film of adhesive into contact with the free face of the porous layer of the other electrode to form an electrochemical couple.
- the first electrode comprising a superposition of two layers simultaneously:
- the electrical separator functions as the electrical separator to prevent any contact between the active material of the first electrode and that of the second, which is ensured by the second layer constituted by a polymeric material selected for its electrical insulating properties;
- the second porous layer is constituted by a polymeric material which has a physicochemical affinity for the electrolyte.
- the second layer of the first electrode advantageously has a gelled microporous structure which can optimize both the electrical separator function and the electrolyte reservoir function.
- the adhesive is a solution containing:
- the solvent has a boiling point in the range 40° C. to 80° C. and the non-solvent has a boiling point of more than 100° C.
- the mass of the solvent represents 75% to 90% of the total mass of the solvent and the non-solvent and the mass of the polymer represents 10% to 20% of the mass of the adhesive solution.
- the polymer is dissolved in the solvent and then the non-solvent is added to this mixture.
- the adhesive obtained is heated to a temperature at which the polymer/solvent/non-solvent mixture is stable and homogeneous during coating.
- the polymer is advantageously selected from polyvinylidene fluoride (PVDF), polyvinyl chloride (PVC), polymethylmethacrylate, cellulose triacetate (CA), a polysulfone, a polyether, a polyolefin such as polyethylene (PE), polyethylene oxide (PEO), polypropylene (PP) and copolymers thereof.
- PVDF polyvinylidene fluoride
- PVC polyvinyl chloride
- CA cellulose triacetate
- a polysulfone a polyether
- a polyolefin such as polyethylene (PE), polyethylene oxide (PEO), polypropylene (PP) and copolymers thereof.
- the polymer can also be an alloy of polyvinylidene fluoride (PVDF) with a polymer selected from a polysulfone, polymethylmethacrylate, polyvinylpyrrolidone and copolymers of polyvinylidene fluoride and polytetrafluoroethylene (PTFE), polyvinylidene fluoride and propylene hexafluoride and polyvinyl acetate (PVAC) and polyvinyl alcohol (PVA).
- PVDF polyvinylidene fluoride
- PTFE polytetrafluoroethylene
- PVAC polyvinyl acetate
- PVA polyvinyl alcohol
- the polymer is an alloy constituted by an elastomeric polymer and a polymer which swells in the organic electrolyte.
- the elastomeric polymer improves the mechanical properties of the second layer by limiting dimensional variants.
- the elastomeric polymer can be selected from polyurethanes, an acrylonitrile-butadiene copolymer, a styrene-butadiene-styrene copolymer, a styrene-isoprene-styrene copolymer, polyesters and amide block polyethers.
- the polymer which swells in the organic electrolyte must have a certain affinity for the electrolyte but without dissolving in the electrolyte at temperatures in the range 50° C. to 80° C.
- This polymer can be selected from polyvinylidene fluoride and its copolymers, polyacrylonitrile, polymethylmethacrylate, polyvinylformal, polybutylmethacrylate and polyvinyl chloride.
- the polymer is preferably polyvinylidene fluoride.
- the solvent is selected from acetone and tetrahydrofuran.
- the non-solvent is selected from butanol, propanol and ethylene glycol.
- the electrochemical couple formed is rolled, dried for 10 minutes at a temperature of about 20° C. and then vacuum dried for about 12 hours.
- the adhesive is a paste constituted by the electrochemically active material of the porous layer of the second electrode, a polymer and a solvent which dissolves the polymer.
- the polymer is preferably selected from polytetra-fluoroethylene, carboxymethylcellulose, hydroxypropyl-methylcellulose, hydroxyethylcellulose, hydroxypropyl-cellulose, polyvinylidene fluoride and its copolymers, polyacrylonitrile, polyacrylic acid, polyacrylamide and mixtures thereof.
- the solvent is selected from water and N-methylpyrrolidone.
- the porous layer of the second electrode and the first layer of the first electrode are produced using the usual methods, such as depositing a paste on a conductive support.
- the conductor support is an expanded metal, a grid, a fabric, a strip or a metal sponge, based on copper or aluminum, for example.
- the paste used to produce the porous layer of the second electrode or the first layer of the first electrode advantageously has the same composition as the adhesive of the invention, constituted by the electrochemically active material of the porous layer of the second electrode, the polymer and the solvent which dissolves the polymer.
- the electrochemical couple formed is rolled and then dried for 10 minutes at a temperature of about 80° C.
- the thickness of the porous second layer of the first electrode used in the first or second variant of the process of the invention is preferably in the range 15 ⁇ m to 100 ⁇ m.
- the adhesive is a porous film with a thickness which is preferably in the range 5 ⁇ m to 20 ⁇ m.
- the thickness of the first layer of the first electrode and the thickness of the porous layer of the second electrode are advantageously in the range 100 ⁇ m to 160 ⁇ m.
- the porosity of the porous layers in each electrode is advantageously in the range 30% to 95%, preferably in the range 35% to 40%.
- the electrode comprising the superposition of two layers used to carry out the process of the invention is produced by first producing the first layer and then coating the first layer with a film of a solution of the polymer selected to constitute the second layer. The film is then dried to eliminate the solvent or solvents constituting the polymer solution.
- the electrode comprising two layers is produced by means of phase inversion by immersion.
- the solution is the polymer dissolved in a solvent.
- the first layer is then coated with a film of the solution and the film is brought into contact with a non-solvent which is miscible with the solvent.
- the electrode comprising two layers is produced by means of phase inversion by evaporation.
- the solution is the polymer dissolved in a volatile solvent to which a less volatile non-solvent which is miscible with the solvent is added in a proportion which is insufficient to cause precipitation of the polymer.
- the second layer of the electrode comprising two layers from the solution used as the adhesive in the first variant of the process of the invention described above.
- FIG. 1 shows the evolution of the voltage of the cell of the invention during cycling; the cell voltage in volts is plotted on the ordinate axis and time in hours is plotted on the abscissa axis.
- FIG. 2 shows the evolution of the ratio of the discharge capacity of the cell of the invention in the Nth cycle to the discharge capacity of the cell in the first cycle during cycling. This ratio, which is less than unity, is plotted on the ordinate axis and the number of cycles N is plotted on the abscissa axis.
- a paste constituted by 12% by weight of graphite powder, 2% by weight of polyacrylic acid and 86% by weight of water was prepared.
- the paste was obtained by mixing polyacrylic acid in water for about half an hour at room temperature, with stirring. When the solution was translucent the graphite powder was incorporated and stirring was continued until the mixture was homogeneous.
- Expanded copper was then coated with this paste and the electrode was placed in an oven at 80° C. for 2 hours.
- the graphite electrode obtained comprised a porous layer of graphite and polyacrylic acid with a thickness of 140 ⁇ m and with 40% porosity.
- An electrode comprising a first layer containing LiNiO 2 as the electrochemically active material was coated with a solution of 75% by weight acetone, 12.5% by weight butanol and 12.5% by weight polyvinylidene fluoride.
- This solution was obtained by dissolving the polyvinylidene fluoride in acetone and then adding the butanol.
- the LiNiO 2 electrode was then dried at a temperature of the order of 20° C. for 12 hours.
- the electrode comprised the superposition of a first layer containing LiNiO 2 and a second layer constituted by polyvinylidene fluoride.

- the adhesive-coated electrode was immediately assembled with the graphite electrode produced previously.
- the electrochemical couple obtained could optionally be rolled or simply placed between two metal plates under pressure to render the thickness of the adhesive film uniform.
- the electrochemical couple was dried at room temperature for 10 minutes and then vacuum dried for 12 hours before being impregnated with an electrolyte composed of a solution of LiPF 6 with a concentration of 1 M in a mixture of propylene carbonate/ethylene carbonate/dimethyl carbonate in a proportion of 1/1/3.
- the electrochemical couple impregnated in this way was mounted in a button cell then cycled at a rate of C/20 for charge and discharge at a temperature of 60° C.

- the electrode comprising one layer of graphite and polyacrylic acid was coated with the same paste as that used to form the layer, the paste acting as the adhesive at this stage of the process.
- the graphite electrode coated with adhesive was immediately assembled with the electrode formed in Example 1 comprising a first layer of LiNiO 2 and a second layer of polyvinylidene fluoride.
